MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary directly from a Google Cloud Storage bucket (storage.googleapis.com/berglas/...) and installs it as an executable. While this is the official upstream distribution channel used by the GoogleCloudPlatform/berglas project (the same bucket is referenced in their official README for installation), it is still a binary blob with only an MD5 checksum (cryptographically weak, collision-prone) rather than a stronger SHA256. The source is not a tagged GitHub release artifact with a verifiable provenance chain. If the GCS bucket were compromised or the object replaced, the MD5 check would not reliably catch a substitution attack. This is a genuine medium-severity supply-chain concern: an executed binary from a non-standard (non-GitHub-releases) host with a weak integrity check, even if the host is operated by Google.

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
